Ability to clean up drop-down pollution in the "Add Tree" dialog with the Delete key.
In the attachment, you will see that I had a series of file types for Texas Instrument projects. Then, I realized that I wasn't getting all the files I needed so I added some file types. This created a new entry which is the one that I need for all TI projects. However, I am stuck with an entry that I will never use again.
